This Video shows simple steps to create a text file from your iOS App. It shows the simple swift code which is written to do create the file in the document directory of the iPhone. It uses Xcode environment to develop and simulate the App in the in-built simulator. It shows the creation of the text file by navigating to the device folder in the library of the Mac OS (host OS) but in the real phone the file should get created in the document folder.
I hope you like this video. For any questions, suggestions or appreciation please contact us at: https://programmerworld.co/contact/ or email at: programmerworld1990@gmail.com
