I don't exactly know how to edit the post if its possible, I found someone who posted a workaround for this but I still would like to know the right way to do this By ArnoldRauers_Tinytouchtales " Edit the Exported Xcode Project Open the Xcode project generated by Unity. In Xcode, navigate to Build Settings and search for OTHER_CFLAGS or OTHER_LDFLAGS. Look for any occurrences of -mno-thumb and remove it."

Im very sorry, I didn't know comments worked this way, I will reply out of comments as you suggest, thanks for telling me so that I can do this correctly. Im using Unity, so indeed I will need to ask elsewhere, thanks. lot for telling about how is the process for Xcode, I may publish something using Xcode too in the future
