FOR ME ALSO

I have tested our sample app in Xcode version 9.4 (9F1027a) with PPiOS-Rename v1.2.0 on macOS High Sierra 10.13.6 (17G65) without issue. So this issue does not appear to be simply caused by running PPiOS-Rename with Xcode 9.4 in High Sierra.

In particular, this error suggests that there is some unexpected condition in code in app being analyzed by PPiOS-Rename. Can either of you (@carusd or @Muhammedayaz77) provide additional detail about what exactly you're doing that caused this issue?

  1. Are you using only Objective-C code? (Swift is not supported.)
  2. What version of PPiOS-Rename are you using?
  3. What is the target version of iOS for your build?
  4. What is the detailed version number of Xcode if different from what I listed (find this info in Xcode > About Xcode)?
  5. Are there unusual libraries that you are using?
  6. What is the target being analyzed, is it compiled for simulator or a device (e.g. x86 or arm)?
  7. Have you tried processing this app with other versions of Xcode or other versions of PPiOS-Rename?

I get the error you are seeing if I try to analyze the binary from a Swift app:

~/Downloads/PPiOS-Rename-v1.2.0/ppios-rename --analyze .../swift-2048.app/swift-2048

Swift is not supported.

Please reopen with additional details if you are seeing this issue with an Objective-C app.
