I need to buy a Mac to run Xcode for iOS app development.If you have an intelbased Mac at your disposal, you can download and install the iPhone SDK, which includes the Xcode IDE, iPhone Simulator, and a suite of.
Iphone Emulator On Mini Simulator And HavingSometimes I am hitting the limits (for example when running an iOS simulator and having too many other programs running at the same time), however I am always able to just close the ones I am not using right now and get everything to run fluently again. Now you can replace your expensive in house device labs with iPhone simulator online for all your manual and automated browser testing needs.I do not have a high budget, which is why I would prefer to buy a (used) Mac with the minimum required specifications that is able to run the latest version of Xcode and iPhone simulator. The app I want to develop is mostly running in the background, so there will be no heavy graphics or computations.Mac and PC Games MacRumors attracts a broad audience of both consumers and professionals interested in the latest technologies and products.There are a lot of different moving pieces, from the device itself to everything that needs to be in place for traffic shaping.The phones themselves pose significant reliability challenges. WebPageTest tries to use real browsers and devices for testing whenever possible, but doing that at scale has some serious challenges, particularly when it comes to testing mobile browsers. I know this has been asked before, but it's been a few years since then, that's why I ask again.iEmulators lets you directly download great emulators for iPhone and iPad without the need to jailbreak. Get apps such as GBA4iOS, nds4ios, AirShou and more hereI'm happy about any comments about RAM, Processor, manufacturing year or anything else.Just wanted to give future visitors an update: I spent a few hours to test macinacloud, however since it felt pretty slow and a bit overcomplicated, in the end I decided to get a used Mac Mini from late 2014 with 8 GB RAM.Thanks to the new M1 chipset, these new devices are a bit of a game-changer when it comes to testing performance.A lot has been made about the M1’s impressive impact on native performance, but for our purposes, what’s most appealing is that now the iPhone, iPad, and new Mac devices all run on the same Arm-based, Apple Silicon chips, bringing a common underlying architecture across the different device types.There was still a lot of work that needed to happen to get the testing results to be as accurate as possible (watch for a post from Patrick Meenan about that in the near future), but the end result is that we can set up new M1 Minis in data centers and use the iOS simulator to enable us to test on different form factors without having to rely on browser emulation. When we do all of our performance testing on one given browser engine, we risk creating a web performance monoculture.Those of you with a keen eye may have noticed that the Dulles location on WebPageTest.org now offers up Mac Mini’s (with the new M1 chip) for testing, using the iOS simulator. Notice how in the image below, Chrome’s waterfall (left) has a stair-step appearance with the resources in the head of the document are requested first, while Safari’s waterfall (right) shows each resource being requested around the same time, regardless of it lives in the head of the document or the body.These behaviors, as well as many other differences, mean that whenever we test performance on an emulated browser using a different browser engine, we’re not getting an accurate reflection of how other browsers perform. Safari and Firefox, on the other hand, each have very different strategies around resource prioritization, causing a very different loading experience from Chrome (and each other).Chrome has a two-phase loading process that limits the number of body resources requested at a time until it has finished parsing the head of the document, while Safari and Firefox will send all requests as soon as they’re discovered. On top of that, each phone you’ve placed in a datacenter for testing must be manually updated whenever a new version of the operating system is released.With all these issues, it’s no surprise that many testing platforms default to using Chrome to emulate different browsers.While Chrome emulation can do things like resize the visual viewport and, more importantly, apply throttling to the network and CPU to simulate different powered devices, it’s still running Chrome under the hood, which means any differences in browser support or optimizations specific to a particular browser will not be reflected in testing.For example, Chrome has taken a very granular approach to apply loading and network priorities to different resource types depending on how those resources are loaded. We don’t have to worry at all about SD cards failing The operating system can be manually updated The M1 Minis also avoid much of the problems we mentioned around deploying mobile devices to data centers: Visual studio for mac asp coreTraffic-shaping is self-contained to the Mac Mini, making it much simpler than on iPhones (which require a separate bridge and WiFi connectivity)The most notable caveat here is that there are limitations in terms of the CPU accuracy for an M1 Mini and older iPhone and iPad devices. We avoid the issue with mobile devices becoming unreachable over USB altogether A single Mac Mini can test the form factors of a wide variety of devices It’s not 100% identical, but it’s impressively close. The median result for the iPhone was 57,491 compared to 60,063 for the Mac Mini.
