Is there any iOS app size inspection tool?

I am working with an iOS app which uses both objective-c and swift code. Currently app IPA size became large. Some resources are included but may not be used in Release IPA. I want to find out which resource should be removed and which resource are making my app size increased unnecessarily. I wonder if there is any such tool or xcode profiler to analyze.

Solution

  • So far the best tool I found is https://github.com/tinymind/LSUnusedResources

    LSUnusedResources

    A Mac App to find unused images and resources in an XCode project. It is heavily influenced by jeffhodnett‘s Unused, but Unused is very slow, and the results are not entirely correct. So It made some performance optimization, the search speed is more faster than Unused.

    Export unused resource list

    Use this tool and export unused/unreferenced resource list into unused.txt

    enter image description here

    Remove references from Xcode .pbxproj file

    Use the below python script to delete references from project.pbxproj file:

        file = open("unused.txt","r")
    data = [line.rstrip('\n') for line in open("project.pbxproj", 'r')]
    newFile = open("project2.pbxproj","w")
    
    def removeLine(imageName):
            temp = data 
            for line_s in temp:
                    if line_s.find(imageName) != -1:
                            data.remove(line_s)
                    else:
                            continue        
             
    for line in file:
            if (len(line) > 5):
                    tokens = line.split("/")
                    len_a = len(tokens)
                    imageName =  tokens[len_a-1]
                    removeLine(imageName.rstrip('\n'))
    
    for line in data:
            newFile.write(line)
            newFile.write('\n')

    And an alternative script, in bash:

        #!/bin/bash

    UNUSED_ASSETS_FILENAME="unused-images.txt"
    XCODEPROJ_PATH="zilly.xcodeproj/project.pbxproj"

    while read LINE; do
      FILENAME="$(basename "$LINE")"
      if [[ $FILENAME =~ (png|jpeg|jpg|gif)$ ]]; then
        echo "Removing '$FILENAME' references from $XCODEPROJ_PATH"
        sed -i '' "/$FILENAME/d" $XCODEPROJ_PATH
      fi
    done < $UNUSED_ASSETS_FILENAME
