Hello, I am trying to build delta. I modified the settings in Signing & Capabilities according to the documentation, but the build still fails with the following error message:

My device information:

OS: macOS 15.0.1
Xcode version: 16.0
Swift version: 6.0
Other info:

I am a novice in iOS development, please let me know if the information I provided is missing.

Thank you.

Same issue, it appears to be a problem with Xcode 16, or at least a warning that became an error in Xcode 16. The Apple Developer Forums and all other available resources said to find and remove the flag, but -mno-thumb is nowhere in the project. However, for reasons unknown to me, the flag -marm includes the flag, even though ti doesn't print in the build logs or response file. And -marm is in the project! Specifically, it's in the DSDeltaCore project. You need to remove this flag from each of the

• Pods/Target Support Files/DSDeltaCore/DSDeltaCore.debug.xcconfig
• Pods/Target Support Files/DSDeltaCore/DSDeltaCore.release.xcconfig
• Pods/Target Support Files/Pods-Delta/Pods-Delta.debug.xcconfig
• Pods/Target Support Files/Pods-Delta/Pods-Delta.release.xcconfig

You may also have to remove it from the DSDeltaCore and libDeSmuME targets build settings under Other C Flags.

It's also in Pods/Local Podspecs/DSDeltaCore.podspec.json, which may be relevant if you're using CocoaPods, but I don't think that affects local builds. It needs to be fixed in the DSDeltaCore repo so it stops automatically adding those flags in the xcconfig files.

That fixes the -mno-thumb, error, at least for me. But after that, I ran into weird errors about Generic parameter 'Datatype' could not be inferred. If you look, they're all on Expressionobjects. I believe this is an **iOS 18** issue, since iOS 18 introduces anExpressiontype in Foundation. This introduces an ambiguity with type inSQLite. To fix _that_, just add SQLite.to all unscopedExpression` calls.

Finally, this got Delta to build, but it crashed with No entry point found. Checked '(null)'. This occurs before AppDelegate even runs, so I do not believe it is a storyboard entry point issue. The stack trace included something about debug dylibs. To fix that, I had to set Enable Debug Dylib Support to No in the top level Delta project build settings. I have no idea if that will cause problems elsewhere, but I successfully installed Delta on my phone after this.
