Brace Placement (Control Structure)

Curlybrace with one space

if (someInstance != nil) {
    //do stuff
}

while (isTrue) {
    //do stuff
}

switch (type) {
    //do stuff
}

Curlybrace with new line

if (someInstance != nil)
{
    //do stuff
}

while (isTrue) 
{
    //do stuff
}

switch (type) 
{
    //do stuff
}

Curlybrace with no space

if (someInstance != nil){
    //do stuff
}

while (isTrue){
    //do stuff
}

switch (type){
    //do stuff
}

Brace Placement (Methods)

Curlybrace from new line

- (void)clearAllDataWithCompletionBlock:(void (^)(NSString *))block 
{
    //do stuff
}

Curlybrace on same line

- (void)clearAllDataWithCompletionBlock:(void (^)(NSString *))block {
    //do stuff
