the same issue.

[alucardulad]

you can try Code Generation->Compilation Mode set Incremental. but I try and did not work

It's because in Xcode 16, UITextField, they add a new function with the same name onReturn. It's ok when you compile and run, but will return error DeadArgSignatureOpt when archive.
The workaround is to change it to a different name (ex: onReturns)

It worked for me, please add the fix in the next update
