I currently have a string containing a path to an image file like so:
/Users/user/Library/Developer/CoreSimulator/Devices/Hidden/data/Containers/Data/Application/Hidden/Documents/AppName/2017-07-07_21:14:52_0.jpeg
I'm trying to retrieve the full name of my image file like so: 2017-07-07_21:14:52_0.jpeg
How would I get the substring starting after the last / to the end of the file path?
I've seen questions related to using substrings:
- Swift: How to get substring from start to last index of character
- How does String substring work in Swift 3
- Substring from String in Swift
However, the provided answers did not help me with my specific problem.
I'm sure it may be something very simple, but all I keep getting is the wrong range of substrings.
Thanks!
Martin R :
To answer your direct question: You can search for the last\noccurrence of a string and get the substring from that position:\n\nlet path = \"/Users/user/.../AppName/2017-07-07_21:14:52_0.jpeg\"\nif let r = path.range(of: \"/\", options: .backwards) {\n let imageName = String(path[r.upperBound...])\n print(imageName) // 2017-07-07_21:14:52_0.jpeg\n}\n\n\n(Code updated for Swift 4 and later.)\n\nBut what you really want is the \"last path component\" of a file path.\nURL has the appropriate method for that purpose:\n\nlet path = \"/Users/user/.../AppName/2017-07-07_21:14:52_0.jpeg\"\nlet imageName = URL(fileURLWithPath: path).lastPathComponent\nprint(imageName) // 2017-07-07_21:14:52_0.jpeg\n",
