Is there any way to know my Iphone storage limit while using filemanager?

Solution

  • There is no real limit for file sizes. You can write to the file system until all storage space is used up. You can append a string to a file with:

    FileManager.default.createFile(atPath: filePath, contents: nil, attributes: nil)
let fileHandle = FileHandle(forWritingAtPath: filePath)!
let string = "test"
let data = string.data(using: .utf8)!
fileHandle.seekToEndOfFile()
fileHandle.write(data)
fileHandle.closeFile()
