There is no limit for record file in iPhone. But Before save to Application Document Directory. Check available space on iPhone and then save, so there is less chance to lost files.

Below code for check available free space in iPhone.

-(uint64_t)getFreeDiskspace {
    NSString *folderPath = [[NSBundle mainBundle] bundlePath];
    NSArray *filesArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:folderPath error:nil];
    NSEnumerator *filesEnumerator = [filesArray objectEnumerator];
    NSString *fileName;
    unsigned long long int fileSize = 0;

    while (fileName = [filesEnumerator nextObject]) {
        NSDictionary *fileDictionary = [[NSFileManager defaultManager] fileAttributesAtPath:[folderPath stringByAppendingPathComponent:fileName] traverseLink:YES];
        fileSize += [fileDictionary fileSize];
    }

    NSLog(@"App size : %lld",fileSize);
    uint64_t totalSpace = 0;
    uint64_t totalFreeSpace = 0;
    NSError *error = nil;
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSDictionary *dictionary = [[NSFileManager defaultManager] attributesOfFileSystemForPath:[paths lastObject] error: &error];

    NSError *attributesError = nil;

    NSDictionary *fileAttributes = [[NSFileManager defaultManager] attributesOfItemAtPath:[paths lastObject] error:&attributesError];

    NSLog(@"App Directory size %llu",[fileAttributes fileSize]);

    if (dictionary) {
        NSNumber *fileSystemSizeInBytes = [dictionary objectForKey: NSFileSystemSize];
        NSNumber *freeFileSystemSizeInBytes = [dictionary objectForKey:NSFileSystemFreeSize];
        totalSpace = [fileSystemSizeInBytes unsignedLongLongValue];
        totalFreeSpace = [freeFileSystemSizeInBytes unsignedLongLongValue];
        NSLog(@"Memory Capacity of %llu MiB with %llu MiB Free memory available.", ((totalSpace)), ((totalFreeSpace)));
    } else {
        NSLog(@"Error Obtaining System Memory Info: Domain = %@, Code = %ld", [error domain], (long)[error code]);
    }
//    NSLog(@"DISK SPACE %f",[self diskSpace]);
//    NSLog(@"GET FREE SPACE %lld",[self getFreeSpace]);
    return totalFreeSpace;
}
- (long long)getFreeSpace
{
    long long freeSpace = 0.0f;
    NSError *error = nil;
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSDictionary *dictionary = [[NSFileManager defaultManager] attributesOfFileSystemForPath:[paths lastObject] error: &error];

    if (dictionary) {
        NSNumber *fileSystemFreeSizeInBytes = [dictionary objectForKey: NSFileSystemFreeSize];
        freeSpace = [fileSystemFreeSizeInBytes longLongValue];
    } else {
        //Handle error
        NSLog(@"Error Obtaining System Memory Info: Domain = %@, Code = %ld", [error domain], (long)[error code]);
    }
    NSLog(@"Free Space %lli",freeSpace);
    return (freeSpace);
}

I couldn't find it's max limit but here is a code to limit it to a specific number of seconds so that you can try and catch to find what is the limit

Setting a time limit when recording an audio clip?
