I am creating a Framework in Objective C, Which needs a good constructor pattern

I am creating a Framework in objective C , which has multiple features, where all the features are need to be initialized while instatiating the library instance, where I am also giving flexibility of providing alternate implementation to any of the feature, to acheive this I am using builder pattern as follow, My question is, Which better Design pattern suits here? Or how Can I improve performace/Memory usage, Please suggest me some pattern for this problem

-(instancetype)initWithBuilder:(LibraryBuilder *)builder {
    self = [super init];
    if (self) {
        // allocate feature1 instance
        if (builder.feature1)
            self.feature1 = builder.feature1;
        else
            self.feature1 = [[InterfaceA alloc] initWithLib:self];

        // allocate feature2 instance
        if (builder.feature2)
            self.feature2 = builder.feature2;
        else
            self.feature2 = [[InterfaceB alloc] init];

        // allocate App Configuration instance
        if (builder.feature3)
            self.feature3 = builder.feature3;
        else
            self.feature3 = [[InterfaceC alloc] init];

        // allocate feature4 instance
        if (builder.feature4)
            self.feature4 = builder.feature4;
        else
            self.feature4 = [[InterfaceD alloc] init];

        // allocate feature5 instance
        if (builder.feature5)
            self.feature5 = builder.feature5;
        else
            self.feature5 = [[InterfaceE alloc] init];

        // allocate feature6 instance
        if (builder.feature6)
            self.feature6 = builder.feature6;
        else
            self.feature6 = [[InterfaceF alloc] init];

        // allocate feature7 instance
        if (builder.feature7)
            self.feature7 = builder.feature7;
        else
            self.feature7 = [[InterfaceG alloc] init];

        // allocate feature8 instance
        if (builder.feature8)
            self.feature8 = builder.feature8;
        else
            self.feature8 = [[InterfaceH alloc] init];

 return self;
}
