How to search for any UIWebView component usage inside a current project?

Question

when submitting my latest build, Apple has response with this warning.

ITMS-90809: Deprecated API Usage - Apple will stop accepting submissions of apps that use UIWebView APIs . See https://developer.apple.com/documentation/uikit/uiwebview for more information.

Fyi, I already migrate all UIWebView component to WKWebView component in my project based on Apple recommendation but Apple still response with the same warning.

Is there any ways to search for any UIWebView element that still attached to my project other that using Search functionality inside Xcode?

Answer 1

You can find by using below command lines in your project.

$ cd yourprojectpath

$ grep -r "UIWebView" .

Answer 2

grep -r UIWebView works fine for sources but partially for 3rd party binaries because from one side they can contain references, comments or string data with UIWebView without actually using the API and from the other they can use it but doesn't have any reference about.

To check binaries (app, static libs or dynamic frameworks) you should get symbols table with nm (llvm symbol table dumper) e.g.:

nm staticlib.a | grep UIWebView
0000000100117c38 t +[UIWebView(SCORVCE) load]
0000000100117c30 t +[UIWebView_SCORVCE_Importer import]
0000000100117ea4 t -[UIWebView(SCORVCE) vce_delegate]
0000000100117d54 t -[UIWebView(SCORVCE) vce_setDelegate:]
000000010012880c t -[VCETrack setUsingUIWebView:]
00000001001287fc t -[VCETrack usingUIWebView]
                 U _OBJC_CLASS_$_UIWebView
0000000100640668 s _OBJC_CLASS_$_UIWebView_SCORVCE_Importer
0000000100639f88 s _OBJC_IVAR_$_VCETrack._usingUIWebView
0000000100640640 s _OBJC_METACLASS_$_UIWebView_SCORVCE_Importer
0000000100117ca0 t ___26+[UIWebView(SCORVCE) load]_block_invoke

For frameworks you should do the same with its binary file:

nm MyFramework.framework/MyFramework | grep UIWebView

Finally to be sure that the app doesn't use UIWebView you should make an archive then find your app file (YourApp.app) and run next script inside:

# Check the app with static libraries
echo "YourApp"
nm YourApp | grep UIWebView

# Check dynamic frameworks
for framework in Frameworks/*.framework; do
  fname=$(basename $framework .framework)
  echo $fname".framework"
  nm $framework/$fname | grep UIWebView
done
