I was trying to access temp directory in Swift. In Objective-C, I could use the following code to do so:
- (NSString *)tempDirectory {
NSString *tempDirectoryTemplate =
[NSTemporaryDirectory() stringByAppendingPathComponent:@"XXXXX"];
const char *tempDirectoryTemplateCString = [tempDirectoryTemplate fileSystemRepresentation];
char *tempDirectoryNameCString = (char *)malloc(strlen(tempDirectoryTemplateCString) + 1);
strcpy(tempDirectoryNameCString, tempDirectoryTemplateCString);
char *result = mkdtemp(tempDirectoryNameCString);
if (!result) {
return nil;
}
NSString *tempDirectoryPath = [[NSFileManager defaultManager] stringWithFileSystemRepresentation:tempDirectoryNameCString length:strlen(result)];
free(tempDirectoryNameCString);
return tempDirectoryPath;
}
However, I'm a bit confuse about the type conversion and casting from Objective-C to Swift, such as const char *
or CMutablePointer<CChar>
. Is there any documents that I should look into?
Thanks.
