skiptools / skip Goto Github PK

I'm encountering a peculiar issue where I've implemented an API and successfully populated a list with it. Everything runs smoothly without errors on iOS. However, on Android, it doesn't display anything, and I'm having difficulty understanding what might be missing.

if am using local data it was working only remote data not showing in android

i am posting code where I am facing

// ContentView
struct ContentView: View {

@StateObject var viewModel = ViewModel()

var body: some View {
    NavigationStack {
        List(viewModel.repos, id: \.id) { repo in
            NavigationLink(value: repo) {
                listRow(repo: repo)
            }
        }
        .navigationDestination(for: Repo.self, destination: { repo in
            RepoDetailView(owner: repo.owner)
        })
        .navigationTitle("Repos")
        .task {
            await viewModel.fetchRepose()
        }
    }
}

}

Please do let me know what I am missing

Hey everyone, I want to share my problem and the solution. The command "skip checkup" was not passing all the tests/points, as you can see on the screenshot. I tried everything, from updating all the components like Xcode, dev tools, and command line tools, but nothing was working or helping. The main issue was that my terminal was running with Rosetta. To test this, you can run "brew config," and Rosetta 2 should be false. After removing the checkmark from running with Rosetta and reinstalling all the components, the "skip checkup" passed successfully.

I've got macbook pro m1 2020 / macOS 14.3.1

When the release Showcase.apk in the emulator that uses a PreferenceKey, crashes may occur like:

This is likely coming from PreferenceKey.swift:

self.initialValue = initialValue ?? (key.companionObjectInstance as! PreferenceKeyCompanion<Value>).defaultValue

This seems to be a consequence of the release build's proguard reduction. Changing the Android/app/proguard-rules.pro file to exclude skip classes makes the crash go away:

-keep class skip.** { *; }
-keep class showcase.module.** { *; }

However, it also increases the Showcase-release.apk size to 15.5 MB from 11.1 MB. Similarly, HelloSkip-release.apk jumps from 6.2 MB to 11 MB, which is an undesirable increase in minimum app size.

I suspect this is due to the way kotlin.reflect.full.companionObjectInstance works. I wonder if it would be possible to avoid using reflection to get the companion object, maybe by using @JvmStatic instead.

Discussed in #52

I got various build errors after using skip init. My guess is that at lease the appid and module need to be unique.

  -  skip init --open-xcode --appid=com.lms.log LMSLogModule LMSLog

Couldn't succeed to compile. It stops in the script to build gradle

This error pops up when I run build in xcode, I have Android studio device running.

The PackageSupport.kt file contains package-specific functionality, such as the Bundle.module accessor and named tuple property accessors. When both a source module and the corresponding test module generate their PackageSupport.kt support files, the source's support code will override the test's. This can lead a runtime error about missing Bundle.module or missing tuple accessors.

This only occurs for Android testing, not on Robolectric. The reason is that Robolectric runs tests on the local JVM against the direct file system, so the classloader can handle multiple same-named resources in different locations. However when running against Android, all the modules are bundled together into a single .apk file, which only permits a file at a given path.

For example the SkipUI/src/main/kotlin/skip/ui/PackageSupport.kt contains:

package skip.ui

import skip.lib.*


internal val <E0, E1> Tuple2<E0, E1>.fromIndex: E0
    get() = element0

internal val <E0, E1> Tuple2<E0, E1>.toIndex: E1
    get() = element1

internal val <E0, E1, E2> Tuple3<E0, E1, E2>.x: E0
    get() = element0

internal val <E0, E1, E2> Tuple3<E0, E1, E2>.y: E1
    get() = element1

internal val <E0, E1, E2> Tuple3<E0, E1, E2>.z: E2
    get() = element2

whereas the SkipUI/src/test/kotlin/skip/ui/PackageSupport.kt file contains:

package skip.ui

import skip.lib.*


internal val skip.foundation.Bundle.Companion.module: skip.foundation.Bundle
    get() = skip.foundation.Bundle(_ModuleBundleLocator::class)
internal class _ModuleBundleLocator {}

When running the SkipUI tests on Android, the test's PackageSupport is overridden by that of the source package, and Bundle.module cannot be found with the error:

skip.ui.SkipUITests > testLocalizedText$SkipUI_debugAndroidTest[Pixel_6_API_33(AVD) - 13] �[31mFAILED �[0m
	java.lang.NoSuchMethodError: No static method getModule(Lskip/foundation/Bundle$Companion;)Lskip/foundation/Bundle; in class Lskip/ui/PackageSupportKt; or its super classes (declaration of 'skip.ui.PackageSupportKt' appears in /data/app/~~fjNm2UV8F_xGX6eB3NKBxA==/skip.ui.test-j1sgEbgQZxlDoyR0KOnVbA==/base.apk!classes2.dex)
	at skip.ui.SkipUITests$testLocalizedText$1$1.invoke(SkipUITests.kt:361)

The easiest solution might be to just generate a different file name (e.g., PackageSupportTest.kt instead of PackageSupport.kt) when the transpiled package is a test package, which will allow the two support files to co-exist when packaged into an .apk.

I am getting the above error while running hello-skip application

The string "A\(x)Z" can be used as an ExpressibleByStringInterpolation, but the string with just a single interpolation like "\(x)" cannot.

See the test case at skiptools/skip-lib@f1d42cf

Two adjacent string interpolations:

        XCTAssertEqual("stringstring", intepolate("\("string")\("string")"))

will be transpiled to the Kotlin:

        XCTAssertEqual("stringstring", intepolate({
            val str = StringExpressibleExample.StringInterpolationExample(literalCapacity = 0, interpolationCount = 0)
            str.appendInterpolation("string")
            str.appendInterpolation("string")
            StringExpressibleExample(stringInterpolation = str)
        }()))

But the single string interpolation:

        XCTAssertEqual("string", intepolate("\("string")"))

does not handle interpolation:

        XCTAssertEqual("string", intepolate("${"string"}"))

Add license for the project.
I would like to work on this.

AsyncStream doesn't appear to be supported.

I am now receiving errors when referencing a binding property using key paths. It throws an error in Kotlin, Unresolved reference: name for the line with TextField in the example below. I went back to run things against a couple versions of skip, and I was able to verify things work fine up until (and including) version 0.7.31, and began erroring from version 0.7.32 onward.

Basic example:

struct Item {
    var name: String
}

public struct ContentView: View {
    @State var item: Item = Item(name: "New Item")
    
    public var body: some View {
        BindingView(item: $item)
    }
}


public struct BindingView: View {
    @Binding var item: Item
    
    public var body: some View {
        Section {
            HStack {
                TextField("", text: $item.name)
            }
        }
    }
}

Error after first installation via brew and running skip checkup (with and without --double-check)

Maybe we can provide more info, to help resolving this issue?

Discussed in #4

I tried running brew install skiptools/skip/skip and it installed successfully but when I run skip checkup, issue occured.

Please see logs when running skip checkup -v

xcodebuild: error: The project named "HelloSkip" does not contain a scheme named "HelloSkipApp". The "-list" option can be used to find the names of the schemes in the project. [✗] Archive iOS ipa (16.93s) Error: The file “Payload” doesn’t exist.

Recently found and installed SkipTools and I am already loving it! You guys rock and this is awesome!

However, as I run the application for testing I notice that on the simulators, the app launches with the name "MyExampleApp" when I just want to have it launch with "MyExample" I have looked through the documentation and have removed any indication of where this could be. I have looked around in the info.plist and the one section that I am finding is to change the name here:

Targets > Build Settings > Project Name:

Changing from "MyExampleApp" to "MyExample" produces build errors. I have even tried creating new schemes and to no resolve.

It continuously says that I have derived data builds, however I have completely deleted my entire derived data cache. Attached is a screenshot of the error

Any help would be greatly appreciated!

The following swift:

public struct ValueHolder: Decodable {
    public let x: Int
    public let value: String?
    public let z: Bool
}

transpiles into the kotlin:

class ValueHolder: Decodable {
    val x: Int
    val value: String?
    val z: Boolean

    constructor(x: Int, value: String? = null, z: Boolean) {
        this.x = x
        this.value = value
        this.z = z
    }

    private enum class CodingKeys(override val rawValue: String, @Suppress("UNUSED_PARAMETER") unusedp: Nothing? = null): CodingKey, RawRepresentable<String> {
        x("x"),
        value("value"),
        z("z");
    }

    private fun CodingKeys(rawValue: String): CodingKeys? {
        return when (rawValue) {
            "x" -> CodingKeys.x
            "value" -> CodingKeys.value
            "z" -> CodingKeys.z
            else -> null
        }
    }

    constructor(from: Decoder) {
        val container = from.container(keyedBy = CodingKeys::class)
        this.x = container.decode(Int::class, forKey = CodingKeys.x)
        this.value = container.decodeIfPresent(String::class, forKey = CodingKeys.value)
        this.z = container.decode(Boolean::class, forKey = CodingKeys.z)
    }

    companion object: DecodableCompanion<ValueHolder> {
        override fun init(from: Decoder): ValueHolder = ValueHolder(from = from)
    }
}

and yields the (rather inscrutable) compile error:

The workaround is to rename the value property to something else and assign the corresponding CodingKey to the name back to "value", like so:

public struct ValueHolder: Decodable {
    public let x: Int
    private let _value: String?
    public var value: String? { _value }
    public let z: Bool


    public enum CodingKeys : String, CodingKey {
        case x
        case _value = "value"
        case z
    }
}

Just for test I init new skip xcode project and try to build it, get this error message:
Gradle run error: Optional(SkipDriveExternal.ProcessResult.ExitStatus.terminated(code: 1))

What I am doing wrong? Thank for the answer.

If a Void function has a single-line that invokes another Void function, we transpile it into a single line like: fun x(): Unit = f(), but that raises a compile error because f() returns Unit?.

For example, the Swift:

class Thing {
    var t: Thing? = nil

    init() {
    }

    func go() {
    }

    func optionalCall() {
        t?.go()
    }
}

transpiles into the Kotlin:

internal open class Thing {
    internal open var t: Thing? = null

    internal constructor() {
    }

    internal open fun go() = Unit

    internal open fun optionalCall(): Unit = t?.go()
}

which yields the compile error:

Type mismatch: inferred type is Unit? but Unit was expected

The only workaround is to add another line to the function, like:

    func optionalCall() {
        let x = t?.go()
        _ = x
    }

Command PhaseScriptExecution failed with a nonzero exit code
in a fresh Skip project.

and fail in the beginning. in the previous versions doesn't not have this issue.

This global function is not supported.

I had this issue when running skip checkup.

The swift:

protocol SQLRow : Identifiable {
}

public struct DataItem : Identifiable {
    public typealias ID = Int64
    public let id: ID
    public init(id: ID) {
        self.id = id
    }
}

extension DataItem : SQLRow {
}

transpiles to the Kotlin:

class DataItem: Identifiable<Long>, SQLRow<ID>, MutableStruct {
    override val id: Long
}

internal interface SQLRow<ID>: Identifiable<ID> {
}

Which fails to compile:

Type parameter ID of 'Identifiable' has inconsistent values: Long, [Error type: Unresolved type for ID]

Discussed in #74

This is related to #64 . We want to be able to implement SkipUI.Text like so:

public struct Text {
    public init(_ key: LocalizedStringKey, tableName: String? = nil, bundle: Bundle? = nil, comment: StaticString? = nil) {
        …
    }

    public init(verbatim string: String) {
        …
    }
}

And be able to create the Text with a localized key. When the string contains an interpolation (e.g., Text("Name: \(username)"), then the LocalizedStringKey constructor is inferred correctly. But if just do Text("Name") with no interpolated arguments, the string sent to the String(verbatim:) constructor, which is not what we want.

The workaround is to explicitly use a LocalizedStringKey in the Text initializer, as seen at https://github.com/skiptools/skip-ui/blob/main/Tests/SkipUITests/SkipUITests.swift#L320

How i can add skip in my exist ios project. I can't found any documentation

I have an issue with the HelloSkip base project. I'm unable to compile anything.

I have Android Studio installed and I'm having no problems compiling and running apps in it.
Additionally I have downgraded JDK from temurin-21 to openjdk17 as suggested in the other post.
I also installed kotlin on top of Android Studio using brew install kotlin but to no avail.

Finally, I tried running skip checkup --verbose to get some insight, but nothing interesting seem to point that there is a problem with Kotlin. The log is huge, so I'm adding it as a separate file if it can help debugging. skip_checup.txt

Any suggestions?

I'm begining in skip development. I've created a simple login view with NavigationStack to go between my views.
The problem is that when I have the navigationStack enabled, when I build the application on the android simulator there is a "padding" on top of the screen before my view is displayed:

The only solution I've found is to remove my navigationStack to make the view taking all the android screen.

For more context, here is my Content View code (the login and signup views are almost the same, they just have some spacers and the fields):
`public struct ContentView: View {
@State var status: String = "login"

public init() {
}

public var body: some View {
    NavigationStack {
        switch status {
        case "login":
            LoginView(status: $status)
        
        case "signup":
            SignupView(status: $status)
            
        default:
            Text("User logged in...")
                .navigationTitle("Home")
                .background(.blue)
        }
    }
}

}`

I also noticed that if there is multiple NavigationStack (like one in the ContentView and then one in the LoginView) the top spacing is even bigger (like if they add themselves).

Is there a way to get rid of this space ?

Installation and all the setup was successful but when I try to build the project on Xcode it shows this error and I see no details about the error If I click it.

Command PhaseScriptExecution failed with a nonzero exit code

When an inout parameter holds an optional value, accessing the value in an if let statement doesn't treat it as being unwrapped on the Kotlin side:

    /// Prepares the given SQL statement, caching and re-using it into the given statement handle.
    func prepare(sql: String, into statement: inout SQLStatement?) throws -> SQLStatement {
        if let stmnt = statement {
            return stmnt // already cached
        } else {
            let stmnt = try ctx.prepare(sql: sql)
            statement = stmnt // save to the cache
            return stmnt
        }
    }

The Kotlin compile error is:

Type mismatch: inferred type is SQLStatement? but SQLStatement was expected

The generated Kotlin looks like this:

    internal open fun prepare(sql: String, into: InOut<SQLStatement?>): SQLStatement {
        val statement = into
        if (statement.value != null) {
            val stmnt = statement.value
            return stmnt // already cached
        } else {
            val stmnt = ctx.prepare(sql = sql)
            statement.value = stmnt // save to the cache
            return stmnt
        }
    }

The workaround is to force-unwrap the inout on the Kotlin side:

    /// Prepares the given SQL statement, caching and re-using it into the given statement handle.
    func prepare(sql: String, into statement: inout SQLStatement?) throws -> SQLStatement {
        if let stmnt = statement {
            #if SKIP
            return stmnt! // Skip treats this as an optional
            #else
            return stmnt // already cached
            #endif
        } else {
            let stmnt = try ctx.prepare(sql: sql)
            statement = stmnt // save to the cache
            return stmnt
        }
    }

I'm using Jetbrains Toolbox to install/upgrade android studio, when I ran command skip checkup it said [!] Android Studio not found: brew install android-studio.

Is it possible for a Jetbrains Toolbox user to pass the skip checkup or install Android Studio via home-brew is required?

When building a project with the Skip plugin, the following Xcode errors can occur and halt the build:

Internal inconsistency error: received multiple target ended messages for target ID '6' or received target ended message but did not receive corresponding target started message, while retrieving parent activity in taskStarted message.
Internal inconsistency error: received multiple task ended messages for task ID '8' or received task ended message but did not receive corresponding task started message.

Performing a clean re-build is the only way to work around this. Sometimes this needs to be done multiple times.

There is no obvious trigger for this error – it occurs at random when building a project. I suspect it has to do with Xcode running multiple simultaneous plugins invocations (for all the dependent Skip modules), and having their communication pipelines mixed up somehow. However, since Xcode 15 removed the ability to disable the "Parallelize Build" setting for the scheme, it is not possible to test this hypothesis directly.

This issue is reported by other SPM plugins when run from within Xcode (e.g., SwiftGen/SwiftGenPlugin#15), and has been a bug since Xcode 14.3, and persists through 15.1. See apple/swift-package-manager#6705.

This may be impossible to get around, but technically structs and enums in Swift work the same way, but it looks like trying to mutate an enum instance doesn't work. The following gives me the error "Variable expected" for "this =". I believe it is because the enum is not adopting MutatingStruct.

enum Count {
    case one
    case two
    case three
    
    mutating func reset() {
        self = .one
    }
}

I'm not able to build for some reason, checkup all good, init ok, I clean build folder and deleted derived data but same issue persist

Hello team,
I have an issue on the build of the HelloSkip example project.
I followed your Readme and the skip checkup seems to be ok.

The problem seems to coming from the SkipStone plugin. I trusted the plugin in Xcode but on build the SkipStone output seems to missing.
My ~/.skiptools/skipkey.env file have a valid license key & the Android simulator is launched.

Project init:

Skip checkup:

On build, I always have this error, even with the Showcase example app:

Do you have some recommandations for that?
