View pops automatically when in navigation view
I want to have a navigation view with 3 views where the third view need to pop to the root view when button is clicked.Here is the code I'm implementing: import SwiftUI class NavigationHelper: ObservableObject { @Published var selection:String? = nil } struct View1: View { @ObservedObject var navigationHelper:NavigationHelper = NavigationHelper() var body: some View { NavigationView{ VStack { Text("View1") .padding() Button { navigationHelper.selection = "View2" } label: { Text("Go To View2") } NavigationLink(tag: "View2", selection: $navigationHelper.selection) { View2() } label: { EmptyView() }.isDetailLink(false) } }.environmentObject(navigationHelper) } } struct View2: View { @EnvironmentObject var navigationHelper:NavigationHelper var body: some View { VStack { Text("View2") .padding() Button { navigationHelper.selection = "View3" } label: { Text("Go To View3") } NavigationLink(tag: "View3", selection: $navigationHelper.selection) { View3() } label: { EmptyView() } } } } struct View3: View { @EnvironmentObject var navigationHelper:NavigationHelper var body: some View { VStack { Text("View3") .padding() Button { navigationHelper.selection = nil } label: { Text("Go To Root") } } } } When View3 is opened it pops back to View1 when opened and cannot understand why? For some reason the selection property becomes nil maybe.

Swift Package Manager's binaryTarget with local XCFramework crashes Xcode
Hello, I've create a sample Swift package which uses binaryTarget to add local XCFramework dependency to a package. XCFramework itself contain two static libraries: One for iOS simulator, and one for iOS device. The result is that Xcode 13 crashes, and when build from command line there is an error, that doesn't help much. Here is sample project download site: https://drive.google.com/file/d/1SBw77DwUOlF40EEXEJQr3i9M-afAm4lv/view?usp=sharing Here is the result when building from command line: swift build -Xswiftc "-sdk" -Xswiftc "`xcrun --sdk iphonesimulator --show-sdk-path`" -Xswiftc "-target" -Xswiftc "x86_64-apple-ios15.0-simulator" -v /usr/bin/xcrun --sdk macosx --show-sdk-platform-path /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc -print-target-info /usr/bin/xcrun --sdk macosx --find xctest /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc -print-target-info /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift-frontend -frontend -print-target-info -sdk /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.3.sdk /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift-frontend -frontend -print-target-info /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift-frontend -frontend -emit-supported-features /var/folders/65/b8ghmm157gn3c_m8cnmxbx2r0000gn/T/TemporaryDirectory.WtlPlf/dummyInput-1.swift Illegal instruction: 4 Here is stack trace from Xcode: Process: Xcode [3774] Path: /Applications/Xcode.app/Contents/MacOS/Xcode Identifier: com.apple.dt.Xcode Version: 13.0 (19234) Build Info: IDEFrameworks-19234000000000000~16 (13A233) App Item ID: 497799835 App External ID: 844005016 Code Type: X86-64 (Native) Parent Process: ???

Static libraries into XCFramework
I have number of static libraries, all of them build as a fat library (arm64, x86_64 are architectures). I'm implementing dynamic framework that works with these libraries. They are added into the frameworks with As a requirement from a client comes to have also XCFramework. XCFramework is created successfully but only if EXCLUDED_ARCHS flag is set to YES in Simulator build script. If NO this is the error I'm getting: ... building for iOS Simulator, but linking in object file built for iOS, for architecture arm64. So is this a good approach or could be done better? I've learned today about --library flag on -create-xcframework but don't know whether they fit in my case. Also I was thinking to create XCFramework with static libraries and include it in my library. How about this option? Any advice will be helpful 👍 P.S My framework supports iOS 11, does this mean that I need to have version for armv7 in the static library?
