In iOS App Bundle is the main directory. If you put your file there you can read as such:

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"myFile" ofType:@"txt"];
NSString *testString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
NSLog(@"%@",testString); 

This will read file myFile.txt

How to input a default .txt file into an iPhone through Xcode in Swift

Since it seems you want the file included with your app, do not attempt to manually install the file somewhere on your computer. That only works with the Simulator if you happen to put the file in just the right place.

Instead, add the file to your Xcode project. Then the file will be added to your app's resource bundle. Then you can access the file using NSBundle to get its path. It will not be in the app's Documents folder. It will be in the app's bundle.

My C program reads a text file. When I put it into Xcode it fails. What's happening?

Make sure that the input.txt file is not in the project folders, but in the same folder as the compiled program. You can find this by right selecting the executable under the 'Products' folder in the left pane of Xcode and selecting "Show in finder" and then move your .txt file there, and run it again.

Where to put txt file when running iOS simulator

Drag it into your project. When asked if it should be part of the app target, make sure it is. The result is that when you build the app, the file will be copied into the app bundle and thus will make its way onto the target device as part of the app, where your code can retrieve it, along these lines:

NSString* f = [[NSBundle mainBundle] pathForResource:@"myfile" ofType:@"txt"];
NSError* err = nil;
NSString* s = [NSString stringWithContentsOfFile:f
                                        encoding:NSUTF8StringEncoding
                                           error:&err];

Read .txt file in .c file for iOS

The path to Documentsdirectory is accessible like this in objective-C:

NSString *documentsPath = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES)[0];

When using such a NSString path in C, you have to convert your NSString to UTF8 string:

NSString *fullPath = [documentPath stringByAppendingPathComponent:@"myFile.txt"];
File *f = fopen(fullPath.UTF8String, "r");

Be aware that fopen() C function need to be passed the absolute path to the desired file to be able to open it.

If fopen() returns NULL, you can check what went wrong by checking errno for the error number and strerror() function (from ) to have a human readable explanation:

#include <stdio.h>
#include <errno.h>
#include <string.h>

File *fileHandler = fopen( fullPathToFileAsUTF8String, openMode );
if( fileHandler == NULL ) {
    fprintf(stderr, "File open error: %s\n", strerror(errno));
}
