What are your favorite Xcode Snippets? Add them in the comments.

pns.m

// Property Nonatomic Strong
// Platform: All
// Completion Scopes: ClassInterfaceMethods

@property (nonatomic, strong) <# class_name #> *<# variable_name #>;

weakself

__weak __typeof(self)weakself = self;

These are some of the snippet I use with Dash, I normally use two empty spaces at the end of each snippet to avoid disambiguations

enum

typedef NS_ENUM(__type__, __name__) {
    @cursor
};

ifnotkind

if (!__variable__ || ![__variable__ isKindOfClass:[__class__ class]]) {
    @cursor
}

log

NSLog(@"@cursor");

errorDomain

#define __NAMEERRORDOMAIN__ @"__NAMEERRORDOMAIN__"
typedef NS_ENUM(__TYPEERRORDOMAIN__, __NAMEERRORCODE__) {
    __ERROR1__,
    __ERROR2__
};

s

@""

doc

//! __Description__
//! @param __param1Name__   __param1Description__
//! @return __returnDescription__   

safeselfblock

__block typeof(self) blockSafeSelf = self;

These are great ideas. My favorite ones:

nss

NSString 

nsf

[NSString stringWithFormat:@"<#format#>", <#values#>]

nsl

NSLocalizedString(@"<#key#>", @"<#comment#>")

Quick log (qlog)

NSLog(@"<#message#>");

Log file and method name (method):

NSLog(@"%s", __PRETTY_FUNCTION__);
